Yeah, the fighter is the only clear choice.
I might haste whoever would benefit from a speed boost. The extra attack isn't a big deal but a free dash on top of double move speed could make a big boost depending on play style. Cast a spell with 120ft of movement has options.
If the rogue isn't regularly hitting the foe, hasting them can be the difference between 0 damage and some damage. But since they get a bonus action attack already, they should already be getting sneak attack on their turn so this should be very conditional.
Rogues better choice. Potentially two sneak attacks a round.
